3 Claims. (Cl. 72-16) The present invention relates to a wall construction.

It is well known in the art to make the outer walls of buildings of plates whereby the separating joints on the outer sides of the plates are vclosed by covering boards. It is a prime object of the present invention to provide a wall construction the outer surface of which is evenly plane and not interrupted by any projecting parts.

For this purpose the wall construction according to the invention is characterized in that pre-fabricated Wall plates of heat insulating, light material with water-tight outer covering are secured separately over horizontal elements to a skeleton in such a way that a plane outer surface is obtained which is free from outwardly projecting construction parts and in that the vertical joints of the plates are filled with an elastic tightening material.

Preferablyy the plates which may be rectangular or square may be made of light concrete and may be covered yon their inside also A'by a protecting layer.

By the arrangement of elastic tightening material in the vertical joints small movements of the plates due to heat extension of the skeleton are possible without danger for the tight plate arrangement. Other features and advantages of the invention will bey United States Patent O come apparent from the description now to follow of a preferred embodimentthereof given by way of example and in which reference will be made to the accompanying drawings in which:

Fig. 1 is a vertical cross-section through two superposed plates, and

Fig. 2 is a horizontal' cross-section through two plates of the wall construction laid side by side.

The core 1 `of the pre-fabricated plates of rectangular plan is made of heat insulating light concrete and is provided on its front side with a Water-tight plaster 2, e. g..

a covering of cement mortar, and on its rear side with a hard covering 3 of any suitable .plaster material. The plaster 2 could also be replaced by a water-tight plate or" natural or artificial stone material glued to the light concrete core while the hard covering 3 may be omitted. The upper and lower side of the plates is also covered by a plaster 4. On the lower side of the plates the plaster 2 forms an inwardly chamfered projection 2a while the upper side of the plates is provided at its front portion with a chamfering surface 2b (Fig. l). Moreover the lower and the upper side of the plates are provided with a groove 5. The skeleton of the wall construction has supports 6a which may be made of metal, concrete, reinforced concrete or wood. Horizontal T- beams 6, 9 are secured in spaced relationship from the plates to the supports 6a. The plates are removably secured to the web 9 of said T-bearns For this purpose hook screws 7 are provided, the hooks of which extend vertically and engage the grooves 5 of the plates while their thread portions are inserted through borings in the flange of the beam and grooves in the front faces of the plates. By screwing on the nuts 8 the plates are separately fastened between the vertical hooks of the screws 7 and the'ange of the beam 6. By this separate fastenice ing of each plate the position thereof may subsequently be changed so that the outer surfaces of the plates lie exactly in one plane.

An even simpler manner of fastening the plates to the horizontal T-beams 6, 9 of the skeleton is obtained by welding onto the upper side of the web 9 of T-beam 6, 9 a ledge fitting into the groove 5 at the base of the pltae. Upon mounting of the wall the upper plate is put'with its lower groove 5 onto this ledge, the upper portion of the plate is slipped under the web 9 of the next upper T-beam and is secured there by means of pins or screws. Preadjustment of the plates is rendered possible by inserting into the upper groove 4 of the same plate a further ledge provided With horizontal screw borings and adapted to receive the web 9 of the next upper T-beam Instead of the hook screws 7 use may be made in this case of straight screws traversing the flange of the beam 6, 9 and screwed into the said ledges.

In order to tighten the horizontal joint between the superposed plates tightening strips 10, 11 of elastic material such as felt are glued or otherwise secured on both sides of the Web 9 of T-beam 6, while the forward portion of the joint is filled with a mastic remaining plastic such as artificial resin putty. Fig. 2 illustrates by way ot' example the tightening of the vertical joint between two adjacent plates. In the vertical narrow sides of the plates opposite horizontal recesses 13 are provided as well as vertical rills 14. In the recesses 13 anchor irons 15 serving to connect theplates are secured Iby means of mortar while in the rounded rills 14 paraflinel or tar irnpregnated tightening ropes 16 are arranged. The outer somewhat wider joint portion is filled with a mastic 12 remaining plastic.

By the described mounting of the plates into the wall skeleton 6a, 6, 9 there is obtained a plane outer face of the wall without any constructional portions projecting beyond the plane. The use of elastic tightening material such as the aforementioned mastic for tightening the joints permits small relative displacement of the plates without danger for the tight plate arrangement.

The lateral anchoring of the plates by means of the irons 15 may also be omitted, in which case the separate plates are easily removable from the skeleton. The inner portions of the joints may be lled with elastic filling material such as waste, vegetable 'bers or the like.

The described Wall construction is particularly suitable for use in connection with the manufacture of the outer walls of buildings.
